Craftsman CMHT6650C 4V Cordless Screwdriver Kit

4V Cordless Screwdriver Kit for Light Assembly

This Craftsman CMHT6650C kit includes a 4-volt cordless screwdriver, a charger and eight screwdriving bits. It targets DIYers and technicians who need a compact tool for light fastening tasks around the home or workshop. The integrated LED work light improves visibility in dim areas. An onboard magnet holds spare screws to keep hands free during use.

Practical Limits of 4-Volt Cordless Operation

Maximum no-load speed reaches 600 RPM while variable-speed control operates at 200 RPM for finer adjustment. The lithium-ion battery delivers enough torque for small screws and pilot holes but is not suited for large-diameter fasteners or dense materials. Continuous high-load driving will drain the pack quickly and the tool lacks a hammer function for masonry work.

Rotating Bit Cartridge Defines Everyday Usability

A rotating bit cartridge stores the eight included bits directly on the tool for immediate access without a separate case. The cartridge rotates to present the required bit at the front, reducing downtime when switching between fastener types. If your workflow demands a larger bit selection or specialised driver profiles, the fixed eight-bit capacity may require supplementary storage.
